The top 50 unplayable gambits for computers

Post by Dann Corbit »

These are all labeled as 'Gambits' by some opening books or the like. Computers will fall on their face trying to solve them. I guess that most of them have no playable solution. The first one ("Opening: Blackburne shilling gambit; Variation: Alatortsev") , definitely not.

Are any of these actually playable in general?

I should mention that those with a large postive score should simply not be allowed by the opponent. They are obviously easy wins for the side to move.

On this page, i found this link: http://studimonetari.org/edg/studi.html

with this diagram

Mate in 530 moves
[D]8/3pr1r1/1NP1Pn2/4k1n1/7R/1b2B1q1/3K3N/7Q w - - 0 1

Lutz Neweklowsky:
The solution starts as follows : 1.Bf4+! Qxf4+! 2.Rxf4! Kxf4! till here its simple. But what is the correct 3. move of white? First here is a wrong continuation: ( a Neweklowsky-seduction : 3.Qf1+? Kg3 4.c7 Nge4+ 5.Kd3 Kxh2 6.c8Q Rg3+ 7.Kd4 dxe6 8.Qh8+ Rh7 9.Qxh7+ Nxh7 10.Kxe4 Bd5 11.Ke5 Ng5 12.Qf2+ Kh3 13.Nxd5 exd5 14.Kxd5 and we have a classic remis from the 5-men egtb. One should try this seduction as a test for his computer! So, what is the correct 3. Move? The solution continues like this: 3.exd7! Nxd7! 4.cxd7! Rxd7+! 5.Nxd7! Rxd7+! and now? Only 6.Kc3 !! lead to the victory ( from the 7-men-egtb ) under : http://www.xs4all.nl/~timkr/chess2/diary_16.htm (see 316): one can see whats happening : 522.Qxg5+! now we are in a 6-men-egtb and it's mate in 530. My problem simply starts 4 moves before the 7-men-tb.

Are any of these actually playable in general?

Re: The top 50 unplayable gambits for computers

Post by Dr.Ex »

Dann Corbit wrote:These are all labeled as 'Gambits' by some opening books or the like. Computers will fall on their face trying to solve them. I guess that most of them have no playable solution. The first one ("Opening: Blackburne shilling gambit; Variation: Alatortsev") , definitely not.

Are any of these actually playable in general?
1.e4 e5 2.Nf3 Nc6 3.Nxe5, 1.e4 Nc6 2.d4 d5 3.exd5 Nb4 and the Bxf7+ one's are certainly unplayable. They are not Gambits.
For 1.e4 b6 2.d4 Bb7 3.Bd3 f5 exists a widely known refutation.

The other lines might be playable in human chess.
